I applied TPS renewal and EAD separately.
*1st EAD application*

Rejected Reason
1. because of the outdated version of the I-765 form ( this was my mistake, I accept it)
2. the payment amount is incorrect or has not been provided ( I wrote a check for $410 , $85 for "U.S Department of Homeland Security"

2nd EAD application

I send the current I-765 form and they sent me a rejection letter citing following reason
1.the payment amount is incorrect or has not been provided ( I wrote a check for $410 , $85 for "U.S Department of Homeland Security" as per the USCIS website
3. the eligibility code provided on your I-765 requires proof that an I-821 has been submitted. ( I sent the copy of the TPS approval docs (I-797A notice of action)-- this one was the new reason for rejection which was not mentioned in my first EAD application even though I have clearly sent the copy of TPS approval.

3rd EAD application
On this application , they rejected me for one reason
1. the payment amount is incorrect or has not been provided. ( this time I sent the check to 'US department of Homeland Security' for the amount of $495 instead of two separate checks of $410 and $85)

sajha mitra plz suggest me where did I do mistake? I really need EAD and this has been a frustrating process. I looked at the website , called the USCIS and asked my friends , the fees should be correct but its been rejected several times. or is it just $410 fees ? anyone in same boat or willing to point out my mistake? plz help me out ! thanks
